Yes, clarifying that paragraph is a good idea. The intended 
meaning used to be unambiguous especially given this part:

"If a public module consists of a header file and an 
implementation file (which are both maintained by hand) then it 
is OK to import private modules in the implementation file."

This refers to the fact that some modules (object, core.thread) 
used to have hand-written .di files to separate the public 
interface from the implementations (which made use of rt.* 
imports).

Now that those duplicate .di files have (fortunately!) been done 
away with, I can see how the wording could be unclear without 
that prior knowledge. And in either case, avoiding to use heavily 
overloaded terms ("private"/"public") without further explanation 
is a good idea.

How core is organised internally has little do with whether rt is 
public or not.
